The first, second, sixth and seventh severance lines 74, 76, 84, 86 are arranged so as to be divergent with respect to a transverse direction (defined by fold lines 23b, 25 b, 27 b, 29 b) of the blank 10. In this way when the blank is formed from a material having a grain direction in either the longitudinal direction or the transverse direction the first, second, sixth and seventh severance lines 74, 76, 84, 86 allows traverse at least in part across the grain direction.

It will also be appreciated that none of the plurality of severance lines 60, 70, 74, 76, 78, 80, 82, 84, 86 extend along any of the hinged connections between the panels of the blank 10. That is to say the plurality of severance lines 60, 70, 74, 76, 78, 80, 82, 84, 86 are not coincident with any of the hinged connections between the panels of the blank 10.

The dispenser D may comprise a tear initiation device in the form of a first tab 96 defined in part by the fourth severance line 80 and by a first fold line 92. First fold line 92 extends between the third severance line 78 and the fifth severance line 82. First fold line 92 is substantially parallel to the fourth severance line 80. The tear initiation device may comprise a second tab 98 hingedly coupled to the first tab 96 by the first fold line 92 and to a detachable portion 62 of the top panel 16 by a second fold line 94.

First severance line 74 defines a detachable portion 66 of the sixth end closure panel 24b. Seventh severance line 86 defines a detachable portion 64 of the eighth end closure panel 28b.

The dispenser D comprises an eighth severance line 60 defined in the sixth end closure panel 24b. The eighth severance line 60 is shaped similarly to the first severance line 74. The eighth severance line 60 is spaced apart or offset from the first severance line 74. The eighth severance line 60 is a partial depth severance line.

The dispenser D comprises a ninth severance line 70 defined in the eighth end closure panel 28b. The ninth severance line 70 is shaped similarly to the seventh severance line 86. The ninth severance line 70 is spaced apart or offset from the seventh severance line 86. The ninth severance line 70 is a partial depth severance line.

The top panel 16 comprises a tenth severance line 91a and an eleventh severance line 91b. The tenth severance line 91a extends between the fold line 17 and the sixth severance line 84. The eleventh severance line 91b extends between the fold line 15 and the second severance line 76.

The tenth severance line 91a defines in part a first portion 68a of the top panel 16 which is foldable about the fold line 17 when the detachable portion 62 has been removed. The eleventh severance line 91b defines in part a second portion 68b of the top panel 16 which is foldable about the fold line 15 when the detachable portion 62 has been removed.

The carton 90 can be formed by a series of sequential folding operations in a straight line machine so that the carton 90 may not be required to be rotated or inverted to complete its construction. The folding process is not limited to that described below and may be altered according to particular manufacturing requirements. During loading and assembly of the carton 90, the carton 90 may be orientated such that one of the first and second side panels 14, 18 forms a loading surface. The bases of one or more articles A may be in sliding contact with the loading surface when being inserted into the carton 90. The articles A may be substantially cylindrical in shape and have a cylindrical axis. The cylindrical axis is orientated perpendicularly to the first side panel 14 and may also be orientated substantially vertically.

The main panel 16 forms the top panel (top wall) 16 when the handle structure H is in use as a carrying handle by a user and this top wall 16 is optionally, disposed adjacent to the sides of the articles A. In this orientation the top wall 16 is not disposed substantially planar to the tops or bottoms of the articles A held within the carton 90 In other words the cylindrical axis of the articles A is substantially parallel with the plane of the top wall 16 of the carton 90.

The main panel 12 forms the base panel 12 when the handle structure H is in use as a carrying handle by a user. The main panel 12 may also form the base panel 12 when the articles A are being dispensed from the carton 90 or when the carton 90 is at rest upon a surface such as a shelf. As such, it will be understood that descriptive terms "top", "base", and "side" do not necessarily limit the carton 90 to adopting a particular orientation but serve to distinguish those panels from one another. In other embodiments the cylindrical axis of the articles A may be orientated differently with respect to the top wall 16 of the carton 90. For example, but not limited to, the cylindrical axis of the articles A be may orientated substantially perpendicularly to the plane of the top wall 16 of the carton 90.

Turning to the construction of the carton 90 as illustrated in FIGS. 2 to 5, the blank 10 is folded about the fold line 17 such that the second side panel 18 is disposed in overlying relationship with the top panel 16 and such that the securing panel 20 is disposed in face contacting relationship with the first side panel 14.

Glue G or other adhesive treatment is applied to an outer surface of the securing panel 20. Alternatively, glue G or other adhesive treatment may be applied to a corresponding edge portion of an inner surface of the base panel 12.

The blank 10 is folded about the fold line 13 such that the base panel 12 is disposed in overlying relationship with the securing panel 20 and part of the first side panel 14. The base panel 12 is thereby secured to the securing panel 20.

The blank 10 is thus formed into a flat collapsed tubular structure which can be readily shipped or distributed to a convertor plant, at which the flat collapsed tubular structure may be erected into an open ended tubular structure and loaded with articles A.

The flat collapsed tubular structure may be erected to form an open ended tubular structure by unfolding the first side panel 14 with respect to the base panel 12 such that the first side panel 14 is disposed substantially perpendicularly with respect to the base panel 12.

The carton 90, in its open ended tubular form, may be loaded with articles A through one or both open ends thereof. It will be appreciated that in some embodiments one of the open ends of the carton 90 may be closed before loading the interior with articles A through the remaining open end.

Once the carton 90 has been loaded with articles A the open ends of the carton 90 are closed.

The method for closing each of the open ends of the carton 90 is substantially the same and will be described by reference to closing the first open end.

A first end of the tubular structure is closed by folding the first end closure panel 22a about fold line 23a and by folding the third end closure panel 26a about fold line 27a.

Glue or other adhesive treatment may be applied to a first portion of an inner surface of the second end closure panel 24a. In alternative embodiments glue or other adhesive treatment may be applied to a corresponding portion of an outer surface of first end closure panel 22a.

Glue or other adhesive treatment may be applied to a second portion of an inner surface of the second end closure panel 24a. In alternative embodiments glue or other adhesive treatment may be applied to a corresponding portion of an outer surface of third end closure panel 26a.

The second end closure panel 24a is then folded about the fold line 25a to be brought into contact with the first and third end closure panels 22a, 26a. The second end closure panel 24a may be secured to each of the first and third end closure panels 22a, 26a.

Glue or other adhesive treatment is applied to a portion of an inner surface of the fourth end closure panel 28a. In alternative embodiments glue or other adhesive treatment may be applied to a portion of an outer surface of the second end closure panel 24a.

The fourth end closure panel 28a is then folded about the fold line 29a to be brought into contact with the second end closure panel 24a and optionally into contact with the first and third end closure panels 22a, 26a.

The fourth end closure panel 28a is secured to the second end closure panel 24a. The fourth end closure panel 28a may be secured to the first and third end closure panels 22a, 26a, for example by glue or other adhesive treatment.

In alternative embodiments the second end closure panel 24a may be folded about fold line 25a after folding the fourth end closure panel 28a about fold line 29a. It will be appreciated that in such embodiments the second end closure panel 24a is disposed outermost.

In other embodiments alternative securing means may be employed to secure the end closure panels 22a, 24a, 26a, 28a, 22b, 24b, 26b, 28b for example, but not limited to, mechanical locking devices such as staples or punch locks integrally formed within the end closure panels 22a, 24a, 26a, 28a; 22b, 24b, 26b, 28b.

The process described above in relation to the first end is replicated to close the second end of the carton 90 and is not further described.

FIGS. 2 and 3 illustrate the assembled carton 90 forming a package with a plurality of articles A.

Referring to FIGS. 2 to 5 the carton 90 comprises dispenser D disposed in part in the top panel 16, in part in the end wall formed by the sixth and eighth end closure panels 24b, 28b and in part in the first and second side wall panels 14, 18.

As shown in FIG. 3, when the detachable portion 62/64/66 is removed an opening O is created. The opening O is substantially diamond shaped. A first substantially triangular portion is removed from the top panel 16 and a second substantially triangular portion is removed from the end wall formed from the end closure panels 22b, 24b, 26b, 28b. The second substantially triangular portion comprises a portion of the sixth and eighth end closure panels 24b, 28b and the seventh end closure panel 26b. In order that the opening O is dimensioned large enough such that an article A can be withdrawn from the carton 90, the first portion 68a of the top panel 16 and the second portion 68b of the top panel 16 are folded about fold lines 17, 15 respectively. The first and second portions 68a, 68b of the top panel 16 may be folded prior to removing an article A from the carton 90. Alternatively, the first and second portions 68a, 68b of the top panel 16 are folded in response to, or simultaneously with, removal of an article A from the carton 90.

The first and second portions 68a, 68b of the top panel 16 may be at least partially folded outwardly of the carton 90 when the detachable portion 62/64/66 is removed; the shearing force needed to sever the severance lines 76, 84 may have the effect of displacing the first and second portions 68a, 68b outwardly of the plane of the top panel 16.

When the first and second portions 68a, 68b of the top panel 16 are folded outwardly of the carton 90 the portion of the opening defined in the top panel 16 extends across the full width of the top panel 16. The articles A which extend substantially between the first and second side panels 14, 18 can be easily withdrawn as a consequence, as shown in FIGS. 4 and 5.

It can be appreciated that various changes may be made within the scope of the present invention. For example, the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape. The carton 90 may be provided with only one foldable portion 68a, 68b; an article A may be removed through the opening created in the carton by partially rotating or pivotally moving the article through the opening, the one foldable portion 68a, 68b may be folded outwardly of the carton 90 in response as the article A is withdrawn.

Whilst the foregoing embodiments have been described with reference to a wraparound style carton it is envisaged that the dispenser may be employed in cartons of alternative design such as, but not limited to, fully enclosed cartons, basket carries and top gripping clips.

It will be recognised that as used herein, directional references such as "top", "base", "front", "back", "end", "side", "inner", "outer", "upper" and "lower" do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another. Any reference to "hinged connection" should not be construed as necessarily referring to a single fold line only; indeed it is envisaged that a hinged connection can be formed from one or more of the following: a short slit, a frangible line or a fold line, without departing from the scope of the invention. It can be appreciated that various changes may be made within the scope of the present invention. For example, the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape.

As used herein, the terms "hinged connection" and "fold line" each refers to all manner of lines that define hinge features of the blank or substrate of sheet material, facilitate folding portions of the blank or substrate of sheet material with respect to one another, or otherwise indicate optimal panel folding locations for the blank or substrate of sheet material. Any reference to "hinged connection" should not be construed as necessarily referring to a single fold line only; indeed a hinged connection can be formed from one or more fold lines.

As used herein, the term "fold line" may refer to one of the following: a scored line, an embossed line, a debossed line, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, an interrupted cut line, aligned slits, a line of short scores and any combination of the aforementioned options, without departing from the scope of the invention.

As used herein, the term "severance line" may refer to all manner of lines formed in the blank or substrate of sheet material that facilitate separating portions of the blank or substrate of sheet material from one another, or otherwise that indicate optimal separation locations on the blank or substrate. As used herein, the term "severance line" may refer to one of the following: a single cut line, a single partial-depth cut line (e.g., a single half-cut line), an interrupted cut line, a score line, an interrupted score line, a line of perforations, a line of short cuts, a line of short slits, a line of short partial-depth cuts (e.g., a line of short half cuts), and any combination of the aforementioned options.

It should be understood that hinged connections, fold lines and severance lines can each include elements that are formed in the blank or substrate of sheet material, including perforations, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, a cut line, an interrupted cut line, slits, scores, any combination thereof, and the like. The elements can be dimensioned and arranged to provide the desired functionality. For example, a line of perforations can be dimensioned or designed with degrees of weakness to define a fold line and/or a severance line. The line of perforations can be designed to facilitate folding and resist breaking to provide a fold line, to facilitate folding and facilitate breaking with more effort to provide a frangible fold line, or to facilitate breaking with little effort to provide a severance line.
